today on log truck,log truck gets the upgraded 1995-1997 high volume pump.unlike my '93's with the E9/F5 combo (for a semi high volume setup,better than previous years) which i was informed was galled and no longer any good,i scored this nice used f5/f5 setup on ebay.
i pulled the trangso mod parts and inserted them in the replacement.now it's onto further modding with Superior's E40D Pump Correction Package #K062
so the transgo mods were to address lockup feel.a nice crisp on/off for a more shift like feeling,rather than a semi glide lock in.
now,what this superior kit will do,will provide more lube flow and keep the pump bushing from walking and causing the issues i had with my old pump with an updated bushing with knurls on the back side,and an increased drain back hole built into the bushing.apparently the pump will outflow oem settings at idle with this kit installed.
the kit is also for the latter E40D's (known as the 4r100) as well and comes complete with the devoted parts to "upgrade" the 4R100's pump to act like the E40D's pump,making it act as on/off.since this is the E4,of course i won't be doing anything with that devoted package of parts.
note:
pics of drill/bit are angled only to help show where to drill (so i was out of the way when snapping the pics.) when actually drilling,drill as straight as possible.
